Next year is gonna get real ugly, and I think it will all depend on who wins the Republican nomination.
If Trump gets it, which is very likely, unless the Republican Party puts a moratorium on allowing convicted felons to represent their party in the presidential race, then Biden has a chance of winning re-election, since you'd hope that a good portion of the public would want to keep an insurrectionist out.
DeSantis or Ramaswamy getting the nomination and effectively distancing themselves from Trump would mean Biden is in big trouble, unless Trump makes the bold move of running as an independent candidate and driving his most loyal supporters away from the Republican vote. And I think given how the Republican Party nearly got away with overthrowing the state and placing themselves in charge, America could be very close to a civil war or falling into a totalitarian dictatorship.
